'be of extremely light weight and fit the foot snugly, in the manner of a gloove, in order that the wearer may be practically unconscious of the presence thereof. In the manufacture of such shoes, therefore particular pains are taken to make the upper of the shoe of extremely pliable, lightweight material, such as kidskin and other leathers. To achieve lightness of weight it is customary not to provide al lining. Such materials are stretchable to an undesirable extent and lack resilience, failing to return to normal size after stretching.
It is found that while such shoes may fit the wearers foot perfectly when new, after even moderate use the shoe invariably loses its snug nt because of the violent stretching produced by muscular action together with impregnation of sweat or outside moisture. The wearer may compensate for such stretching to acertain extend by means of the lacing, drawing the shoes more snugly around the instep, but this is only capable cf compensating for stretch transversely of the foot. Longitudinal stretch, on the contrary, cannot be compensated for by any known means and, therefore, a shoe soon becomes too long for the wearers foot and must be discarded because of L foot slippage within the shoe, producing unsatisfactory traction and annoyance.
In accordance with my invention, I have provided means whereby a shoe may be rendered substantially immune to excessive longitudinal stretch and which will, also, greatly limit the amount of transverse stretch. I accomplish this object by applying to the shoe a band of material Awhich will permit a limited amount of give, so that the wearers foot will not feel as Vif it were enclosed in a vise, but, at the same time, will restrict the amount of stretch to a low minimum. Thus, the life of the shoe will be greatly extended because of the elimination of such excessive stretch as has heretofore required early discarding of the shoe.
The band which is applied to the shoe in accordance with my invention extends substantially from toe to heel thereof along both sides of the upper and may be secured to the shoe in various 2 ways. For example, I have found that a shoe embodying my invention may be produced either by sewing the band along its top and bottom edges either to the outside or the inside of the shoe upper; in another arrangement, the band is interlaced from the outside to the inside of the shoe at spaced points.
My invention will be more fully understood by reference to the appended drawings illustrating preferred embodiments thereof, wherein:
l is a side elevational view of a track shoe illustrating a preferredform of my invention;
Figs. 2, 3 and 4 are sectional views taken substantially along the lines 2-'-2, 3--3 .and 4 4-, re spectively, of Fig. 1;
Fig. 5 is an yelevational View similar to lig. l but showing another embodiment of my inven`- tion;
Fig. 6 -is a sectional view taken substantially along the line Ii-S of Fig. 5; and
Fig. 7 `is a fragmentary sectional view taken substantially along the line 1 1 of Fig. 5 but substantially straightened out for convenience of illustration.
The shoe illustrated is in basic structure substantially a standard type of track shoe as known in the United States for many years, although it should be understood, as stated above, that my invention is likewise applicable to shoes intended for other purposes. However, my invention is particularly applicable to shoes of the Oxford or low type, i. e., wherein the shoe iits snugly around the foot and terminates at or about the base of the ankle.
Referring irst to Figs. lJl, inclusive, such a shoe comprises an upper portion IB which, in the embodiment shown, is formed of a relatively thin, soft and flexible kidskin or like material reinforced as at I2 V:tor lacing eyelets i5, the lacing not being shown. The upper is secured as by stitching to a sole I6 and sole and heel taps il, Il'. To enhance the light weight of the shoe the sole` strip I6 may be skived down at the front and there terminated. The usual insole I8 may be provided and also traction members or spikes 2i), as customary in athletic shoes. I also provide a reinforcing heel strip 22 secured at the bottom by stitching (not shown), along the side edges by stitching 23 and at the top by a double row of stitching 2li, the upper portion of said heel strip having wing-like extensions 2t. It will be under-stood that the upper portion Ill lis formed of a single piece of leather which is seamed together as at 28 under the heel strip 22.
Secured to the upper and extending from toe to heel thereof is a relatively wide band of textile fabric material 33. Said material is preferably of such a type as will provide extremely limited stretch in one direction, i. e., longitudinally of the shoe, say, to an extent of the order of about 1%. Such fabric should be of a tightly woven type and various types of weave and various bers may be employed, such as cotton, silk or synthetic fibers such as those known on the market as acetate rayon, nylon, etc. A highly satisfactory weave is that known in the textile industry as webbing which, as seen best in Fig. l, is arranged in such a way that its limited give or stretch is substantially only in a longitudinal direction.
The width of the band S vis such that said band occupies a substantial proportion of the width of the upper from the reinforcing portion l2 to the sole, preferably about one-half or more of said width.
The band 30 is preferably formed of ya single length of material extending uninterruptedly around the heel of the shoe, being secured to the upper I, either on the inside or outside, but preferably on the outside thereby by stitching 33, so as not to be felt by the wearer, and the ends of the band being stitched under the toe of the shoe, as at As an alternative construction, instead of forming the band 35 in one piece, it may be formed in two pieces secured individually by stitching to the upper d at or adjacent the heel, as, for example, under the heel strip 22.
The band 3o functions eectively to limit the amount of longitudinal stretch of the shoe to an extremely low minimum regardless of the amount of flexing action given the shoe by the wearer and regardless of how much moisture may be imparted to the upper leather by perspiration or otherwise. At the same time, the slight yielding permitted by the fabric band 3E, which is slightly resilient, tending to return after stretching to its original length, will add comfort to the wearer because, although his foot will be firmly enclosed in the soft, form-fitting shoe throughout the entire flexing action of the foot, at the same time there will be no uncomfortably tight feeling as if the foot were bound in a vise. The slight yielding permitted by the character of band 3o will negative any such discomfort.
Although, as stated above, transverse stretch can be overcome by increasingly tight lacing during the life of a shoe of this type, in the ordinary shoe there comes a time after some use when the reinforced marginal portions I2 meet because of the stretching of the leather and stretching beyond this point results only in undesirable bagginess of the shoe, for which no compensation can thereafter be made. The substantial width o'f the band Sil prevents such effect, because of the relatively slight width of upper leather not covered by the band.
The upper leather below band 3c, being unreinforced, of course, retains its maximum flexibility and thus may conform perfectly to the curvature of the foot `around the more muscular portions thereof.
In order to prevent still further the stretching of the upper leather at the heel portion, I prefer to secure under the heel strip .22 a band 38 of fabric similar to that of the band 33. The fabric band 38 is preferably arranged with its weave disposed transversely to that of the band 3Q, so that its limited give will be transverselyl of the shoe. Said band 38, may be secured, along itssidemedges,
d either over or under the strip 30, as by stitching 39.
The method of manufacture of the shoe described above will -be obvious from the above description to anyone skilled in the art. Preferably, the bands 3i) and 38 are stitched to the upper lil before the upper is attached to the sole as by stitching 40.
Referring now to the embodiment illustrated in Figs. 5-7, inclusive, the shoe is constructed subv stantially similarly to the shoe of Figs. l-4 in regard to the orthodox parts of its structure, having an upper portion lil and a sole portion i6 and sole taps i9 and i9.
A band 39 of fabric or the like substantially similar to the band 3) shown in the other gures is secured adjacent the toe portion of the shoe as at All' in the same manner described for the other embodiment and extends longitudinally of the shoe to the heel portion 22', being secured thereto in a manner similar to the embodiment of Figs. 1 and 4.
However, in the embodiment of Figs. 5-7 the band 3G', instead of being secured entirely to one side of the shoe upper, is interlaced from the outside to the inside thereof, as seen -best in Fig. 5. Thus, the band 3G is secured to the outside of the shoe adjacent the toe portion, being stitched to the Lipper as at 33', and then extends through a slit 5t into the inside of the shoe. tends unattached to a slit 52, at which point the band passes from the inside back to the outside of the shoe, extending along the outside and stitched thereto at 33 to another slit 54; the band passes through the slit 5t and again extends unattached aiong the inside of the shoe to a slit 55 through which it passes, continuing along the outside thereof and being stitched to the shoe from this point to the heel as in the embodiment of Fig. l. The band 3B is also secured as by stitching 35, 35a., 35h and 35e adjacent the slits zl, 52, 53 and 55.
As a result of the interlacing arrangement just described, the shoe snugly conforms to the shape of the foot and retains this snug iit throughout strenuous flexing, as in running. By leaving the band partially unstitched, close conformity of the band with the foot is maintained despite some stretching of the upper leather.
The band may, of course, be stitched entirely on the inside of the shoe, if desired.
Various changes coming within the spirit of my invention are susceptible of being incorporated without departing from the essential spirit or scope thereof. Hence, I do not wish to be limited to the particulars of the accompanying illustrations and drawings nor by the language chosen in the foregoing description, except to the extent indicated in the appended claim.
